This invention relates to equipment for cleansing, washing and rinsing operations incidental to the washing of utensils.

This invention has utility when embodied in a re-circulatory washer, scrubber, rinser, and drier as adapted for the handling of dishes and cooking utensils.

Legs 1 are shown as supporting base 2 as a Mounted on this base 2 is a housing having back 4, sides 5, and front opening 6. This front opening may be closed by doors 7, 8, hinged to the sides 5, and doors 9, 10, to fold thereover, are hinged respectively to top 11 and adjacent the bottom 2. Adjustable means 12, 13, act as frictional clamps at the hinge mountings for the doors 9, 10, to hold such doors open or in closed position for the retention in this housing of the hot liquid, as soapy water for washing, or clear hot water for rinsing of the dishes or ware.

or hot plate or- 17 having shaft 18 carrying pulley 19 about which downwardly extends drivin belt 20 I to pass about groove pulley 21 he (1 by set screw 22 fast with shaft 23 mounted in bearings 24, 25, carried by inward extension 26 from the housing back 4. The motor 17 thus provides through its connections a drive for the shaft 23. This shaft 23 extends into the housing toward the opening 6, and is provided with a detachable tubular portion 27 go constituting a multi-stream projecting nozzle having therein vanes 27. This tubular portion 27, which may be unthreaded in' removal for cleaning, has openings 28 as outlets for the ets orstreams of liquid. Tufted a about on the face of this cylinder nozzle 27 in the region of these openings 28 are bristles or scrubbers 29 so that this is a rotary scrubber device, which, as thus far described, may be effective in carrying out desired cleansing. 10 operations in the scrubbing of ware wherein the food or other material is peculiarly adherent, as in cooking utensils. The articles may be held directly over the nozzle in position for the scrubbing to occur or the may be carried by removable rack 30 crew shown as having various supporting regions 31, 32, 33, 34, 35, 3e, 37. This rack with the articles therein may be removed from the housing and inserted independently of ad justing the brush 27.

By means of crank 38, the article receiving I portion 37 may be moved in the housing to shift articles of cutlery thereon against the brush. Material which is removed, as well as washing or rinsing liquid, may pass through the rack portion 36 and thus the more solid matter may be accumulated in drip pan 39 instead ofpassing down to the pan 2 for discharge by way of the drain 3. This pan 39 may have the water accumulation drained therefrom by removing plug 40. The rack 30 may be removed from the housing after the "articles have drained into the pan 39.

The sediment may, thereafter, be removed from this pan 39. The handle or crank 38 has clearance 41 between the doors 7, 8, so that the doors me? be closed with the handle protruding and ree to be operated.

Below the door 10 there is provided rockable handle 42 for rod 43 mounted in brackets 44, 45, carried adjacent the bottom 2 of the housing and extending to the rear thereof. This rod 43 adjacent the back 4 of the housing carries crank 46 from which upwardly extends link 47 to arm 48 mounted on fixed bearing 49. This arm 48 serves as a lever having at its free end beyond the link 47 pin 50 coacting with grooved collar 51 in the chamber 26 from the back. This collar 51 is fast on downwardly extending shaft 52. This shaft 52 adjacent its lower extremity carries fixed collar 53 and thercbeyond has a centrifugal impeller 54- curved as to its face so that normally there is a'pull action downward on this shaft 52 for drawingfriction wheel 55 adjacent the collar 51 into diiVQ ing engagement with friction wheel56fast with the pulley 21. Accordingly, with the handle 42 rocked downward the collar'51 is so shifted that the friction wheel 55 is in driving engagement with the friction wheel 56. With the motor 17 operating the scrubber, the impeller 54 is effective for liquid circulation operating upon submergence in the liquid. Between the collar 53 and the impeller 54, the shaft 52 carries spider 57 mounting bell 58 about the impeller 54. This bell 58 has bottom opening 59.

Upwardly extending from this bell 58 is duct section 60 telescoping within duct section 61, each about the shaft 52. This duct section 61 is within the housing 4, 5, 6, rigid therewith, and provided with supplemental duct section 62 as a branch from the upper portion terminating in an outlet about the shaft 23 disposed to discharge into the nozzle 27. For starting washing operations,

the handle 42 is operated to effect descent of this impeller 54 and bell 58 from retracted position in bell 63 in the housing. In this shifting, the impeller 54 descends into screened well 64 in reservoir compartment 65. As herein shown this compartment 65 is semi-cylindrical in form and has companion rinsing compartment 66. These compartments 65, 66, are assembled to form a cylindrical unit by flange 67 and pins 68. As so assembled for relative rotation as to rectangular carrier or support 69 they may be angularly shifted from the front of the housing. This shifting is done only when handle 42 is raised to have the bell 58 in the bell housing 63.

The sliding of the reservoir structure 65, 66, with its support 69 into assembly position with the washer housing is along guides 70 which carry rear stop 71 as well as supplemental base support 2.

When the structure is mounted on the legs 1 as supports, these reservoirs 65,66, may have the liquid, as wash water and rinse water, maintained at the desired temperature by burner 73 controlled by Valve 74. When the structure is mounted directly on a hot plate or stove the control of such stove may determine the degree of heating of the rinsing liquid, as well as the washing liquid.

By turning on switch 75, the motor 17 may be started. If the operation be that of washing, the position of the compartment reser- V011 65, 66, in the angularly shifted position determined by handle 76 before the descent of the bell 58, should be with the bell 58 to enter the well 64. The impeller pump brings about water circulation and sprays such upon the articles in the rack 30 exposed to the operation of the nozzle 27. \Vhen the desired washing action, or scrubbing has been completed, the handle 42 may be operated to lift the impeller 54. The closed circuit of the liquidis thus discontinued. However, it is well to allow a little time after cutting out this washing circuit for the drainage of the washing liquid back'through the opening 3 into the vessel compartment 65 before angularly shifting the-reservoir compartment to bring the rinsing reservoir section 66 below the bell 63. When this changed position has occurred, the handle 42 may be thrown downward into positionlocking the frame against removal as well as the handle 76 against shifting angularly. In this position the circulation of the rinsing water starts forthwith and may be continued for the desired rinsing interval, when the motor may be shut off at switch 75. This automatically discontinues the circulation of the rinsing liquid as well as the operation of the rotary nozzle 27. Inasmuch as the water or liquids have been maintained at high temperature during this operation there is no necessity for drying the articles or ware. Such may be remvoed from the housing by taking the rack 30 therefrom and the articles are accordingly self drying due to the high temperature which has been used.

By mounting on threaded stem '77 on the shaft 23 buffer Wheel 78 or other rotative equipment there may be polishing or even redressing of the articles of kitchen equipment.

The handle 76 for the reservoir having the compartments 65, 66, in its angular shifting when the pump is lifted therefrom, may snap into seats 7 9, 80, or 81 (Fig. 7), thereby disposing partition 82 between compartments 65, 66, in position to have the drain 3 and the bell 58 for the pump on the same or common side of the partition 82 shown in Fig. 8 as in the wash chamber or reservoir 65. \Vith the handle 76 shifted clockwise to position 83, the bell 58 may be in position for the impeller 54 to lift rinse water from the reservoir portion 66 and discharge such rinse water by drain outlet 3, into the wash water reservoir 65. With the handle 76 shifted still further clockwise to seat 81, the partition 82 is in position 84 so that there is recirculation of the rinse water. For convenience in shifting the housing 1 to various positions, handles 85 are provided. For convenience in shifting the rack 30. it is provided with pendently of said repository for rendering the delivery means inoperative.
